title: Urinary protein excretion is associated with left ventricular hypertrophy in treatment-naïve hypertensive patients in an african hospital setting.
abstract: BACKGROUND
  Left ventricular hypertrophy (LVH) is an independent predictor of fatal and non-fatal cardiovascular events in hypertensive patients. Current guidelines for the management of hypertension are based on cardiovascular risk stratification. This study evaluated the possibility that an inexpensive, simple random, single-void urinary protein-to-creatinine ratio (UPCR) would be associated to left ventricular (LV) mass in a black African setting, and therefore direct appropriate management of these patients.
  
  
  METHODS
  We measured echocardiographic LV mass and a random spot UPCR in 34 untreated newly diagnosed hypertensive patients attending the cardiology consultation unit at the Yaoundé General Hospital. LV mass was indexed to height (in m(2.7)) to obtain the LV mass index (LVMI). A regression model was used to verify the independent association between UPCR and LVMI.
  
  
  RESULTS
  The mean age of our patients was 52.65 years, and the mean systolic and diastolic blood pressures were 152.44 and 92.84 mm Hg, respectively. The prevalence of LVH was 41.2%. UPCR was higher in patients with LVH compared to those without (p = 0.043). There was a significant correlation between UPCR and LVMI (r = 0.581, p < 0.001). In the multiple linear regression model, UPCR was associated with LVMI independent of systolic blood pressure (p < 0.001).
  
  
  CONCLUSIONS
  Random spot UPCR is associated with an increased LV mass and may be very useful in screening and guiding appropriate management of high-risk untreated hypertensive patients.
